TURNTABLE. v

Application led June 10, .1924, Serial No. 719,031. Renewed Il'uly, 2, 1927.

AMy invention relates to improvements in a turn-table -adaptedfor display purposes. The object of my invention is to provide a turn-table suitable for displaying an automobile or other merchandise in a show room or window; a further object is to construct a turn-table adapted to be rotated slowly for displaying the merchandise and providing suitable mechanism for rotating the same; a further object is to construct a turntable in detachable sections making it portable, and adapted to be readily taken apart and assembled for shipping purposes; a still further object is to construct a turn-table having a substantial base and a central bearing which will support the turn-tabley in a balanced position without securing the base to the floor; a still further object is to form the turn-table ofk structural frame work which is light in weight and sufficiently rigid to supporta heavy automobile or truck, and

. astill further object is to construct the turn table with a relatively high central portion and relatively low down supporting track sections adapted to carr a vehicle in a position close to the iioor t us providing ample room for the Central bearing and rotating mechanism. t

Referring to the accompanying drawing, Fig. 1, is a side elevation showing my improved.. turn-table, and indicating in dotted lines an automobile thereon; Fig. 2, is a plan View ofv 1; Fig. 3, is a longitudinal vertical section, on line 3--3 Fig. 2; Fig. 4, is a transverse vertical section onV line 4-4, Fig. 2, drawn on `a larger scale; and Fig. 5, is a transverse vertical section on line 5-5 Fig. 2, drawn on a larger scale. i Referring to theV accompanying drawings, in which like reference characters refer to like parts, 1 represents a base and 2 represents the turn-table rotatably mounted upon said base.v The base 1 consists of a large flange out being'secured thereto. Centrally posi tioned upon the Hange'?) is an upright shaft 5, having a shoulder 6l upon which Vis rota# tably supported the central bearing block 7 of the turn-table.

Ball bearings 8 and 9 are interposed between the shift 5 and said block 7 to reduce the friction and permit of an accurate adjustment for holding the turn-table in a horizontal plane. The top ofthe shaft 5 and the bearing block 7 are elevated, as much as the free space under an automobile 3, adapted to rest upon the floor, with-V will permit, thus allowing y ball kbearings 8 and 9 to be widely separated so as to supi port the turn-table in a horizontal plane,

'without tilting sufficient-ly to scrape the floor when revolving, thus eliminating the use of a circular track heretofore required.

The bearinr block 7y is rigidly secured between parallel I-beams 10 rand 11, which latter are secured to cross-pieces, or I-beams,

12 and IBbyangle-plates 14, thus forminga rigid rectangular bearing frame` unit, which is detachably mounted upon the 1 and to which are detachably secured the track units of the turn-table, hereafter described. y 'f `The track units 15 and 16, each consist of a track 17 formed of channel iron, which extends the entire length of the turn-table-A Each track 17 is bent, as shown in Figs. 1 and 3, thus forming an elevated central section 18,' inclined sections 19 and horizontal supportind end sections 20, whichv latter are positioned5 close tothe floor. The wheels 22 of the automobile may be run over the elevated sections 18 of the tracks and` brought into a balancedl position upon the end sections 20, as indicated in dotted lines Fig. l, The opposite end sections 20 of each tracky 17 are connected by two relatively heavy angle-irons 25 and'26.y The ends of eachan le iron are rigidly secured tothe end sections 20 of the channel iron forming the track Said track 17 and said two angle irons 25 and 26 are thus rigidly secured together and form a rigid truss construction adaptedto be'supported centrally and carry the'weightof a heavy load` upon the supporting end sections 2O of the track.

Theftrack unit-S15 and 16are adapted to be detachably secured upon the ends of the cross-pieces or I-beams 12 and 13, by bolts 28, positioned on opposite sides of each of said cross-pieces. Saidbolts 28 have coun# ter-sunk heads located in the elevated centralportion 18 of the track 17, and the lower ends of said bolts pass through the space between the adjacent edges of the angleirons 25 and 26, and also pass through holes 33 to said tracks. By removing the bolts 33 and 28, each track unit may be detached from the rectangular bearing frame unit formed by the bearing block 7 and the niembers l0, l1, l2 and 13.

The cross-pieces l2 and 13 of the bearing frame unit are spaced a sufficient distance apart to permit thel track units to be rigidly secured to said bearing frame unit and thus insure the track units against anyvertical orrtilti-ng movement.

rIhe mechanism for rotating the turntable comprises a gear wheel B5, secured to under side of the bearing block 7, and a pinion 36 meshing with said gear 35. The pinion 36 is carried upon a shaft-'37 mounted in a bearing 38, secured uponA the base flange 3. A worm-wheel 39 is also mounted upon saidl shaft 37' and is rotated by a motor 40 through' al worm l1 meshing with the worm-wheel 39; A friction clutch 42, of any standard type is interposed between the worm wheel- 39 and the pinion 3G, adapted to relieve the motor from a sudden strain-when starting the turn table in m0- tion.

The operation of my invention is as follows: The motor vehicle is run upon the tracks of the turn-table by first placing inclined blocks, or skids, under the ends of the tracks toA support the same under the unbalanced strain. The front, or rear, wheels of the vehicle are run over the'inclined and relevated sections of the tracksso that the vehicle may be placedA in a balanced position on the'turn-table, as indicated in Fig. 1. The motor l0 is then started and the power is lapplied through the rotating mechanism for slowl-'y rotating the turntable, the rigid pivot shaft the turn-table, with a heavy vehicle thereon, may be slowly and continuously rotated by a very small electric motor The centra-l bearing, having two widely separatedpoints of support upon a relatively long upright shaft, arranged asl shown in the drawing, will hold the turn table in a horizontal plane', so that the weight of a person stepping into or out of an automobile mounted on the turn-table Will not tilt the latter. using a circular supporting track is thus avoided. By kconstructing the turn-table in detachable units the same may be readily transported. Any other'line of merchandise may be displayed upon the turn table without departing from my invention.
